The Early Years of Radio Astronomy: Reflections Fifty Years after Jansky's Discovery

Radio astronomy has revolutionized the process glossy astronomy. Marking the 50th anniversary of Jansky's discovery in 1933 of extraterrestrial radio emission, Professor Sullivan requested some of the pioneers within the box to set down their models of occasions and the folk who made them. all of the ranking of individuals seeks to provide an outstanding 'feeling' for the days to the good majority of readers who don't have skilled them. Over one hundred fifty illustrations, more often than not old images of guys and machines, liven up many of the memories and reflections. The checklist of individuals contains a number of the key personalities and covers all of the significant laboratories and nations concerned with radio astronomy earlier than 1960. as well as the radio astronomers themselves, there are contributions from optical astronomers and theorists heavily on the topic of the sector, in addition to historians of 20th century astronomy.

The Fatal Strain: On the Trail of Avian Flu and the Coming Pandemic

A riveting account of why technological know-how on my own can’t cease the following pandemic

Outbreaks of avian and swine flu have reawakened fears that had lain dormant for almost a century, ever because the influenza pandemic of 1918 that killed not less than 50 million humans around the world. while a hugely deadly pressure of avian flu broke out in Asia lately and raced westward, the Washington Post’s Alan Sipress chased the rising possibility because it infiltrated distant jungle villages, mountain redoubts, and teeming towns. He tracked the virus throughout 9 international locations, looking at its secrets and techniques time and again elude the world’s brightest scientists and such a lot intrepid sickness hunters. Savage and mercurial, this novel influenza strain—H5N1—has been referred to as the kissing cousin of the Spanish flu and, with quite a few genetic tweaks, may well kill hundreds of thousands of individuals. None folks is immune.

The deadly pressure is a fast-moving account that weaves cultural, political, and clinical strands right into a story of inevitable epidemic. In his brilliant portrayal of the fight among guy and microbe, Sipress chronicles the accelerating variety of close to misses and explores the harsh dynamic that has usually made Asia the fountainhead of killer flu lines. much more than glossy medication, it's chook smugglers, battling cock breeders, and witch medical professionals who may possibly be sure the evolution of this viral risk via permitting it to reproduce and dashing it on its way.

The ease of foreign go back and forth and the fragile stability of today’s worldwide economic climate have left the area prone to pandemic in a fashion the sufferers of 1918 may possibly by no means think. however it is human failings that can pose the best peril. Political bosses in kingdom after state have lined up outbreaks. historic customs, like buying and selling in reside bird and the ritual free up of birds to earn non secular benefit, have didn't adapt to the microbial risk. The world’s filthy rich nations have left poorer, frontline international locations with out cheap vaccines or different guns for confronting the sickness, fostering a feeling of complaint that endangers us all.

The chilling fact is that we don’t have command over the H5N1 virus. It maintains to unfold, thwarting efforts to uproot it. And because it does, the viral cube proceed to roll, threatening to supply a plague pressure that's either lethal and will unfold as simply because the universal chilly. Swine flu has reminded us that flu epidemics take place. Sipress reminds us whatever some distance worse should be brewing.
